Content Completion in SQF
Oxygen XML Editor helps you edit Schematron Quick Fixes embedded in a Schematron document by offering proposals that are valid at the cursor position in a Content Completion Assistant. It can be manually activated with the Ctrl + Space shortcut.
When you edit the value of an attribute that references a Quick Fix
      ID, the ids are collected from the entire definition scope. For example, if the editing
      context is assert/@sqf:fix, the Content Completion Assistant
      proposes all fixes defined locally and globally.
If the editing context is an attribute value that is an XPath expression (such as
        sqf:add/@match or replace/@select), the Content
        Completion Assistant offers the names of XPath functions, the XPath axes, and
      user-defined variables and parameters.
The Content Completion Assistant displays XSLT 1.0 functions (and optionally
      XSLT 2.0 / 3.0 functions) in the @path, @select,
        @context, @subject, and @test attributes,
      depending on the Schematron options that
      are set in Preferences pages. If the Saxon namespace
        (xmlns:saxon="http://icl.com/saxon") or the Saxon namespace is declared in
      the Schematron schema (xmlns:saxon="http://saxon.sf.net/") the content
      completion also displays the XSLT Saxon extension functions.
